If you pre-order the game you will be allowed into the world of Hyboria several days prior to the official opening of the servers, which is set for May 20th in North-America and May 23rd in Europe. This is what we call the Early Access program.
By pre-ordering the game from a retailer that retailer will supply you with a pre-order key. You can use this key to purchase Early Access from the Funcom website for $5 / 5€.
Note that Early Access is exclusively available to those who pre-order. The characters you create during your Early Access period will still be available to you once the servers officially open. Early Access will require you to download the game yourself.
The dates for Early Access are as follows:
Europe: Registration and sales of Early Access open on May 2nd. Download of the client for early access from May 16th, and you can start playing from May 20th.
North-America: Registration and sales of Early Access open on May 2nd. Download of the client for early access from May 13th, and you can start playing from May 17th.
Purchasing Early Access will not only give you the chance to jump into Conan’s world before the rest of the world, but it will also give you ten extra days of free play time. These ten days are added to your thirty days of free play that is included in the retail
If you have not received your pre-order key by they end of April please contact your retailer directly.
